Secret Cold War tests in St. Louis raise concerns

ST. LOUIS (AP) — Doris Spates was a baby when her father died inexplicably in 1955. She has watched four siblings die of cancer, and she survived cervical cancer.

After learning that the Army conducted secret chemical testing in her impoverished St. Louis neighborhood at the height of the Cold War, she wonders if her own government is to blame.

In the mid-1950s, and again a decade later, the Army used motorized blowers atop a low-income housing high-rise, at schools and from the backs of station wagons to send a potentially dangerous compound into the already-hazy air in predominantly black areas of St. Louis.

Local officials were told at the time that the government was testing a smoke screen that could shield St. Louis from aerial observation in case the Russians attacked.

But in 1994, the government said the tests were part of a biological weapons program and St. Louis was chosen because it bore some resemblance to Russian cities that the U.S. might attack. The material being sprayed was zinc cadmium sulfide, a fine fluorescent powder.

Now, new research is raising greater concern about the implications of those tests. St. Louis Community College-Meramec sociology professor Lisa Martino-Taylor's research has raised the possibility that the Army performed radiation testing by mixing radioactive particles with the zinc cadmium sulfide, though she concedes there is no direct proof.

But her report, released late last month, was troubling enough that both U.S. senators from Missouri wrote to Army Secretary John McHugh demanding answers.

Aides to Sens. Claire McCaskill and Roy Blunt said they have received no response. Army spokesman Dave Foster declined an interview request from The Associated Press, saying the Army would first respond to the senators.

The area of the secret testing is described by the Army in documents obtained by Martino-Taylor through a Freedom of Information Act request as "a densely populated slum district." About three-quarters of the residents were black.

Spates, now 57 and retired, was born in 1955, delivered inside her family's apartment on the top floor of the since-demolished Pruitt-Igoe housing development in north St. Louis. Her family didn't know that on the roof, the Army was intentionally spewing hundreds of pounds of zinc cadmium sulfide into the air.

Three months after her birth, her father died. Four of her 11 siblings succumbed to cancer at relatively young ages.

"I'm wondering if it got into our system," Spates said. "When I heard about the testing, I thought, 'Oh my God. If they did that, there's no telling what else they're hiding.'"

Mary Helen Brindell wonders, too. Now 68, her family lived in a working-class mixed-race neighborhood where spraying occurred.

The Army has admitted only to using blowers to spread the chemical, but Brindell recalled a summer day playing baseball with other kids in the street when a squadron of green Army planes flew close to the ground and dropped a powdery substance. She went inside, washed it off her face and arms, then went back out to play.
